Description of holotype Body slender; head longer than wide, snout round in dorsal view and protruding in lateral view; nostrils slightly protuberant, directed laterally; canthus rostralis distinct; loreal region weakly concave; tympanum distinct, large, diameter about 2/3 eye diameter; weak supratympanic fold; well developed lateral vocal sacs; vocal slits present; tongue medium-sized; vomerine teeth in two small series, between and behind choanae; choanae small. Arms robust; thumb without nuptial asperities or spines; subarticular tubercles single, round; outer metacarpal tubercle nearly round, inner metacarpal tubercle elliptical; finger discs medium sized, nearly round; finger length I = II < IV < III; fingers laterally fringed; upper surfaces of finger discs without well developed scutes; finger and toe discs of about equal size. Legs moderately robust; foot with an ovoid inner metatarsal tubercle and a protruding round outer metatarsal tubercle; subarticular tubercles single, round; toes extensively fringed laterally; extensive tarsal fold-flap continuous distally with toe fringe on outer side of first toe. Dorsal skin texture slightly rugged; undersurfaces smooth; rugged texture near the vent. Color in life of the holotype: Dorsum dark brown; upper surfaces of thigh, tibia, and foot reddish brown with dark transverse bars; forearm reddish brown Â?with dark spots; light line extending from the eye to the groin; dark brown lateral stripe extending from tip of snout, through nostril, eye, and tympanum to near arm insertion; a whitish lateral stripe below the dark brown stripe extending from tip of snout to the arm insertion; lips dark; throat and belly whitish with dark brown marbling; iris cupreous. Color in preservative of the holotype: In preservative (alcohol 70%), the colors are similar to those in life, except for the reddish-brown areas and iris that Â? become brown. Measurements of the holotype: snout-vent length 27.1; head length 10.9; head width 9.1; eye diameter 3.8; eye-nostril distance 1.6; tympanum diameter 2.1; tight length 14.0; tibia length 14.3; foot length 14.4. Variation In life, the whitish lateral stripe may be yellowish. Measurements, (mean, range) in mm of three males: snout-vent length 27.6, 27.1-28.5; head length 10.8, 10.7-10.9; head width 9.2, 9.1-9.3; eye diameter 3.8,3.8; eye-nostril distance 1.7,1.6-1.8; tympanum diameter 2.3, 2.1-2.6; tight length 14.0, 13.8-14.3; tibia length 14.4, 14.3-14.5; foot length 14.2, 14.1-14.4.
